4.5.11 Configuring BPDU Cop
In the following procedure, STP and BPDU Cop are set up on an interface (0.23 on a GE24POE line card), with
at first the default TIMEOUT value (10) used.

None If there is an unexpected BPDU, feature is
activated. The interface is disabled and must
be re-enabled by the user
Normal
(no faults)
Y n = 1..2048
(Auto-recovery
enabled)
None If there is an unexpected BPDU, feature is
activated. After n minutes, the system will
re-enable the interface.
Fault State Y n = 1..2048 User changes BPDU-
COP to N
The fault is cleared immediately (interface is
re-enabled) by the system, but the feature is
now disabled.
Fault State Y n = 0 User changes BPDU-
COP to N
The fault is not cleared (user must re-enable
interface), and the feature is now disabled.
Fault State Y n = 1..2048 User changes n to 0 Fault is not cleared (user must re-enable
interface), and the fault will not clear auto-
matically the next the feature is invoked.
Fault State Y n = 0 User changers to a non-
zero value
Auto-recovery is being invoked, and once
the command is accepted the system will
wait n minutes and re-enable the interface.
Fault State Y n = 1..2048 User changes n to
another value
The previous value is used for system
recovery, and the new value is used the next
time
